In particular, Table 2 shows other blending examples of red, yellow, blue, and black edible coloring materials which are particularly preferable as inks for writing instruments.

[Table 2]

The blending examples shown in Tables 1 and 2 are preferable blending ratios at the time of blending, and change after long-term storage and after color design formation. During long-term storage, the proportion of volatile substances such as ethanol and isopropyl alcohol is generally reduced and the proportion of other materials is generally increased. Further, in the coloring material after being formed into a color design, it is expected that the vehicle will be dried and the coloring material will be the main component.

These edible coloring materials form a color design by drawing a pattern, letters, a pattern with a brush or a brush or spraying them directly on a food or on a sheet or the like attached to the food. It may be provided to do.
Further, it may be provided so as to form a color design by being printed by various methods on the surface of a food product or a sheet body attached to the food product. With the present edible coloring material prepared for the three primary colors and black, various colors can be formed by using only these four types of coloring materials.

The edible coloring material is preferably leasably held in various coloring material holding bodies. As the edible coloring material holder, various known office tools, working tools, drawing materials, etc. can be used.For example, an ink filling shaft used in an ink pen such as a felt-tip pen or a cartridge used in a fountain pen can be manually used. It may be in a form used for a writing instrument that is used while being carried. Or various printing machines,
It may be formed in a cartridge applicable to a printer, a plotter, and a copying machine, and is preferably a cartridge used in an ink jet printer. Also, like a stamp table, a colored material holder in a form in which an appropriate amount of edible coloring material is leached out by being pressed by a member such as a stamp for forming a color design and adhered to the stamp pressing surface. But good.

For example, the ink filling shaft is a shaft-shaped member in which a large number of plastic fibers are bundled, and the outer periphery of the shaft is covered with a plastic film so that an appropriate pressure is applied. By dipping one end of this ink filling shaft in the liquid of the edible coloring material, a predetermined amount of the edible coloring material can be sucked up and held by the capillary phenomenon. The ink filling shaft is mounted on the pen shaft as in the conventional case, and the edible coloring material in the pen tip portion is leached out by using the pen tip by pressing it against the paper surface or the like. As a result, the edible coloring material on the end side opposite to the ink filling shaft moves to the pen tip side and gradually leaches out.

When the edible coloring material holder is a pen or a stamp table, if the edible coloring materials 1 to 3 or 5 to 7 in Tables 1 and 2 which can be mixed with each other are used, for example, immediately after applying one color. Can be mixed and toned by applying another color on top of. Therefore, the color design of various colors can be achieved by variously adjusting the degree of color mixing.
Further, it goes without saying that the edible coloring materials of the three primary colors may be mixed in advance at a predetermined ratio and the edible coloring material toned to a predetermined color may be filled.

Further, in the ink jet type printer,
The edible coloring material is filled in cartridges of various ink jet printers and is leached so as to be jetted in predetermined amounts. For printers, preferably Tables 1, 2
It is preferable that the edible coloring materials 1 to 8 shown in FIG. Since the edible coloring materials 1 to 8 have the fluidity, quick-drying property, and easiness of bleeding that are suitable for use in an ink jet printer, various kinds of printing similar to those using conventional inks can be performed. , A color design can be formed. In particular, edible coloring materials 1 to
Nos. 3 and 5 to 7 are colored magenta, cyan, and yellow, respectively, so that clear images and precise patterns can be printed in the same manner as in the case of using a normal color ink of three colors. A design can be formed.

The coloring material and the coloring material holder of the present invention can be used as a writing instrument as usual for various purposes similar to known inks such as office work and work. In addition, for example, when applied to a coloring book for infants, there is no health problem even if the infant accidentally grips or sucks in the mouth, which is preferable. Moreover, even if it is used on a part where a creature such as a pet may be licked, it is less likely to damage the health of the pet. In addition, edible paper (Japanese Patent Application No. 11-34600)
(See Japanese Patent Publication No. 232854), it is possible to provide a highly safe stationery or a stationery for infants. It can also be used to form edible paper into colored paper or to produce colored paste by adding the ink of the present invention to edible paste, and produce edible stationery rich in color. be able to.

It goes without saying that it can be used for the purpose of forming a color design on food. For example, if a coloring material holding body such as a pen that holds the present edible coloring material is set in a confectionery making kit or the like, an individual can create a food with a unique color design, which increases fun.
